Currently I am trying to use my summarizer service with my orangepi. I was getting
504 Gateway Timeout errors all the time, because orangepi is slow for calculations. I thought it is related with Finatra , but found out it was Nginx. It has default 75 seconds. For fixing it, you have to create ne file and then restart nginx service.
proxy_connect_timeout 600; proxy_send_timeout 600; proxy_read_timeout 600; send_timeout 600;
Now It will wait 5 minutes!
sudo systemctl restart nginx.service
